Myinvention relates to a novel method of- .-of g'tlie'United States, residing at Hoboken, in theeountyof Hudson and State of New Jersey, haveinlventedcertain and useful Im- ,Etion of the' invention, such as will enab e otlfrerslskilled in the' art to which it appertains layin'g'cement parquette floors, the object befi'ngtQ'prov-ide means for so laying the oors `1'5 as Lto-'produce a pattern -of any desired kind 'and colorsand making same absolutely withut interstic'es between the divisions or tiles,

. thereby making same absolutely water roof,

and,enabling same to be handsomely mshed; and Vit`'co'nsis'ts in the various steps or operations-hereinafter fully described and claimed.

I .''LI`1`1.tlie..accompanying drawings, illustrating,myinventiom- Figure 1 is a plan view of a yfloor 4constructed in accordance with 'my n1ethod; Fig. 2 is a section of same on `the linej2'2 ofFig. 1.

Fig. 3 is a plan viewshowing. a floor in plan in a three-color pattern.

.My'invention relates more particularly to floors of magnesia cement, but may be applied-'to the construction of floors of any other .-A'ieoor laid in accordance mamy inves-vy ation therefor. -My-method consists in first laying-upon la door or, other suitable foundation A a lager of cement/B.' -,-The said layer B is prefere -magne'sia icem'ent, for the reasonthat such cement has greater Aadhesive properties than -tofwood as' welll'as to stone, concrete, blick,

" "net cijack orfhipl as lreadily'. f The said &'c'. 'f `.1t' 'is1 .alsol` preferable by reason of the fact tirati-tis more elastic, harder, and more dura-ble than .Portland for 'other cement and lay' rgBis-smqthed'or leveled on the surface,

caoutchouc, or other material to which the cement will not adhere, .such plates being secured in place b nails or in any other suitable Avmanner, and a 'acent rows thereof are relatively staggere The-spaces or squares vD between said plates are then filled with the cement of one color to the height of kthe plates C, .an'd said "cement is thenv allowed to set.` i

The said plates C arevthen removed, and cement of another coloris introduced in the spaces left thereby a d filled in ilush with the first-laid squares a d allowed to set.I The cement thus introduced not only bindswith the layer B, but the'various squares bind own and finished as desire ,A 'i

tern. lThis method maybe employed i-n reproducing patterns in three or .more colors and in imitation of anykind of tiles, as illus- 'trated in Fig. 3,- it being necessary after firstl drawinthedesign on the layer B toblock out Wit a three-color design and fill in the remaining en `-re'movin *the plates F end lling in the third '..color'zt e complete pattern is reprof colors and-anypatternrmaybe thus readily reproduced'andA 'at lthe same 4time a oor of superior qualitypr'oduced.
